HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 236,578, dated January11, 1881.

Application filed July 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, HAMLINE H. HAGER- MAN, of \Vest Windsor, in thecounty of Richland and State of Ohio, have invented a new and usefulImprovement in Hay Rakes, of which the following is a specification,reference being had to the accompanying drawings.

The invention relates to an improvement in horse hay-rakes; and itconsists in the elements hereinafter fully described, and particularlypointed out in the claims.

The object of the invention is to provide a revolving horse-rake havingspring attachments and capable of being revolved by power from the axleof the carriage, subject to the control of the operator.

Referring to the accompanying drawings, Figure 1 is a top view of a rakeembodying the elements of the invention. Fig. 2 is a plan view, from therear, of same. Figs. 3 and 5 are plan views of the obverse and reversesides of the wheel N. The remaining figures are detached views of theparts indicated by letter hereinafter.

Aindicates the main axle, and B the supporting-wheels.

D indicates the carriage, consisting of the sides a, mounted at theirfront portions upon the axle A, and the cross-bar E, connecting the saidsides directly in front of the axle.

Upon the upper surface of the bar E are hinged the shafts F, whichextend forward a suitable distance, and are connected at their rear bythe cross-bars c (1.

Upon the face of the bar E, prefer-ably at its center, is secured thehanger m, which passes forward beneath the cross-bar d, and has pivotedin its bifurcated end the lower end of the threaded bolt 0, extendingvertically upward through an aperture in the bar (I, being providedbeneath the same with a nut, m, and directly above the same with aspiral sprin g, f, then a washer, h, and lastly with a nut, i. The nutson i will preferably be of such form that they may be readily operatedby hand, the nut i being, by preference, formed with a horizontalcrank-handle, a, by which it may be rotated.

Between the rear ends of the sides a is mounted upon short axles t therake head or bar H. The axles t are journaled in suitable boxes providedfor them, and enter the metallic bushings a, secured on the ends of therake-bar H, whereby the said bar is retained in place and made capableof revolution.

Upon the front edge of the bar H are secured, at equal distances fromeach other, the horizontal sleeves to, in which are inserted the frontends of the rake-teeth ac, said ends being bent at an angle, so as toenter the sleeves and permit the rear portions of the teeth, which curverearward and downward, to have a vertical oscillating movement and toadapt themselves to any unevenness in the surface of the ground.

Upon the rear edge of the bar H are secured, at points opposite to thesleeves w, the vertical guides I, through which the teeth as pass asthey extend rearward from the sleeves. The upper ends of the guides Ienter or are in close contact with the bar J, adj ustably secured bybolts across their upper ends. Around the guides I, between the teeth wand the bar J, are placed the coiled springs K, the tension of whichretains the teeth in proper position, but permits them at the same timeto haveaslight verticalspringing movement when in use. Upon the removalof the bar J any of the teeth may be detached and replaced at will. Thebar H will be secured a sufficient distance in rear of the axle A toallow the teeth 00 to sweep clear of the latter when revolved.

At the left-hand end of the bar H, upon the short axle t, is secured theratchet L, and upon the side to adjacent to it the spring-pawl M, whichengages the ratchet L and operates to prevent the rake-bar moving on theaxles t in a direction contrary to that indicated by the arrow. If itwere not for the pawl and ratchet, the bar H, when the rear portion ofthe frame D is elevated to pass over a stone or other obstruction, wouldtilt rearward, and thereby throw the points of the teeth a," upwardunder the carriage, out of position. The use of the said pawl andratchet effectually avoids this.

Upon the right-hand end of the axle A is mounted the band or chain wheelN, carrying upon one side the right pawl a and upon the other the leftpawl b, the former of which engages the ratchet-wheelc,rigidlysecuredupon the axle A between the wheel N and the side a, while the pawl bengages the ratchet d, secured upon the inner face of the hub of thewheel B. The purpose of this arrangement is, that when the machine istraveling forward, the movement of the wheel B willbe communicated tothe wheel N, and when traveling backward that the wheel N shall not beaffected bythe movement of either the wheel B or axle A.

Upon the short axle t, at the right of the machine, and on the outsideof the bar it, is mounted so as to freely revolve thereon the band orchain wheel P, which is directly opposite to the larger wheel N, and hasformed upon its inner face one half of the clutch-box R. The other halfof the clutch-box R is rigidly secured to the axle t and rotates withit. A chain or band, S, connects the wheels N P, so as to communicatemotion from one to the other.

Across the front part of the machine, extending along the front bar, E,is journaled the rock-shaft T, upon the middle portions of which issecured the arm V, extending upward, and connected by a rod, W, with afootpiece, X, hinged to the bar 0.

Upon the ends of the shaft T are attached the vertical arms at, havingaffixed in their upper ends the rods n, which pass rearward over thesides a and connect with the arms t, pivotally secured on the outeredges of the sides a, as shown with sufficient accuracy in Fig. 1.

Upon the lower end of the pivot securing the arm t, on the left-handside of the machine, is secured an arm, u, which extends rearwardbetween the side of the wheel P and the face of the cam 20', formed onthe face of the inner half of the clutch-box R.

When it is desired to operate the machine the shaft T is turned slightlytoward the rear, so that the ends of the arms t will be below the frontedges of the ends of the bar H and prevent the rake turning, the rakebeing then in proper position to gather the hay. When the arms t aremoved rearward the arm a is by the same movement forced outward, whichdisengages the halves of the clutch-box R, causing the wheel P to runidly upon the axle t. The rake being set in position, as aforesaid, bythe arms 1%, the machine is drawn forward, when the teeth 00 will gatherthe hay. During this movement themotion of the wheels B is communicatedto the wheel N, and thence, through the chain or band S, to the wheel P,

,which at this period, as aforesaid, runs idly I upon the axle t. Aftera sufficient quantity of hay has been gathered the driver presses uponthe foot-piece X, which operates to draw the arms t from beneath the barH and to remove the arm u from contact with the wheel P, which movementpermits the halves of the clutch-box R to come together, whereby themotion of the wheels B is communicated, through the wheel N, chain S,and wheel P, to the axles t and bar H, causing them and the teeth 00 torevolve toward the front, dropping the hay gathered in a bundle. At theend of each revolution of the rake-bar and teeth the arm at is forcedoutward against the wheel P by the cam'w coming in contact with it,disengaging the clutch R, and throwing the arms t beneath the rake-barH, whereby the teeth a," are again held in position to gather hay. Thisoperation may be continued as long as desired, until all the hay hasbeen gathered and deposited in heaps.

By rotating the nuts m 2' either to the right or left the rear of thecarriage-frame may be tilted either upward or downward, and the pointsof the teeth w thereby adjusted at will with relation to the ground.

What Iclaim as my invention, and desire to secure by Letters Patent,is-- 1. In a hay-rake, the hanger 9c and pivotallysecured bolt 0,passing upward through the bar d, and provided with nuts m i and springf, for the purpose of adjusting the rake-teeth with relation to theground, substantially as specified.

2. In combination with a revolving rakehead, the clutch-box B, wheels NP, connected by a chain or belt, cam to, arm a, and a means foroperating the said arm to open or close the clutch-box It, substantiallyas set forth.

3. The foot-piece X, connected with the rockshaft T, the rods n, arms t,and arm a, in combination with the clutch-box H and wheels N P,connected by a chain or belt, and with the revolving rake, substantiallyas specified.

In testimony that I claim the foregoing improvement in hay-rakes, asabove described, I have hereunto set my hand this 31st day of May,18:50.
